When Is Fiber Not Fiber?

Three British broadband providers have asked the nation's advertising authority to stop competitors from describing DSL and cable services as "fiber."

Hyperoptic , Gigaclear and CityFibre are angry that BT, Virgin Media Inc. (Nasdaq: VMED), Sky and other communications service providers and cable operators describe their networks -- typically a combination of fiber to the cabinet and copper or coax for the last-mile connection to the home -- as fiber, according to ISP Preview UK.

For nine years, the Advertising Standards Authority (ASA) has allowed providers to use the term "fiber" to describe hybrid-fiber networks, including Virgin's hybrid fiber and coax solution, and the hybrid fiber optic and twisted pair copper infrastructure that Openreach uses.

While many consumers may not know the underlying technologies powering their broadband connections, they connote fiber with enhanced service, according to responses by research groups conducted by Opinion Leader.

"Participants typically understood that a full-fiber service represented a step-change in the quality of their broadband -- in speed, reliability and consistency -- and felt misled by products delivered over copper phone wires or cable being advertised as 'fiber,' " Opinion Leader Director Neil Samson told The Register.

One research panelist compared fiber to a high-end car and alternatives to a bus. Yet even when researchers explained the different technologies in use, participants could not discern which products providers' advertisements promoted, the Register reported.

Several Members of Parliament also consider widespread use of the term fiber to describe all broadband as misleading. ASA is reviewing Britain's Advertising Codes and expects to release an update this summer.

What Really Matters
While fiber is crucial to ultra-broadband and plays a key role in all deployments, limiting providers to using the term fiber for all-fiber networks only addresses the linguistic part of the issue. Surely performance is the most important criteria?

After all, if consumers use DOCSIS coax cable, they should attain 30 Mbit/s like their full-fiber neighbors, unless the cable is over-provisioned, ThinkBroadband wrote. And VDSL can reach the same speed, unless interference -- from lightning, perhaps -- forces a resynchronization. Service providers have a slew of other differentiating technologies, such as IPv4, IPv6 and Cat5e Ethernet cable.

Regardless of what completes the last mile, newer technologies continue to push the speed and latency envelope as vendors seek to eliminate fiber's edge. Using "fiber" as a synonym for fast, low latency service to the detriment of other technologies could be equally misleading to the general public.

Deutsche Telekom just signed an infrastructure project with the Gigabit Region Stuttgart, home to 174 municipalities and almost 3 million people, one of many partnerships the German operator has inked in its bid to grow revenue and business.

Mobile and cable operators represented half the managed SD-WAN services market share in this fast-growing space, while other broadband providers such as ISPs and satellite operators also appeared on Vertical Systems Group's ranking.

By slashing subscriber pricing by more than $30 billion annually, Low Earth Orbit satellite companies led by Jeff Bezos and Elon Musk as well as OneWeb have the potential to usher in a whole new era of broadband.

In this insightful Light Reading radio show, Kurt Raaflaub, Head of Strategic Solutions Marketing, will outline the key service provider challenges, deployment considerations, next-gen Gigabit technologies, and service models to win market share in the rapidly growing MDU market.

The MDU market continues to face fierce competition among service providers due to tech-savvy residents (i.e., millennials), demand from building owners and management companies, plus the favorable economics of bulk contracts. However, no MDUs are the same, so service providers must use multiple technologies and inconsistent deployment models, increasing operational complexity and rollout costs.

The MDU market itself is evolving as residents adopt smart-home technologies, generating rising demand for smart apartments with built-in connected thermostats, keyless entryways and doors, and video doorbells. This evolution presents both new challenges and opportunities. In other words, service providers must consider innovative service-delivery strategies to compete and win.

In this Broadband World News and ADTRAN webinar, Kurt Raaflaub, Head of Strategic Solutions Marketing, will highlight emerging MDU broadband Internet trends and challenges. In addition, Kurt will outline the next-generation service creation and delivery platform, built on open standards, that allows service providers to connect millions of underserved MDUs, enables creation of user-driven services, and reduces operational complexity and costs.

Plus, special guest, Alice Lawson, Broadband and Cable Program Manager for the City of Seattle, will discuss Seattle’s B4B-Build For Broadband initiative that addresses best practices in planning for MDU telecommunication infrastructure.
